debate. paul will have it over the next couple years with marco rubio and others in the senate. there will be more rand paul type candidates running. i think it's healthy for the party to have the debate. i agree with the caller more than he would think. i have never been for shutting down debate or ruling out different points of view in the party. i think a help the party does challenge its own assumptions. in this case i really think we will see out of president obama the great cost from retreating from the world. host: if he runs, marco rubio would have to give up his senate seat. in the wall street journal -- she writes that it will take a stand of unity to fight president obama. can the gop in washington now develop those things? guest: i don't think we can assume there will be unity. you should not just cast a vote for the sake of unity. there are some issues where you can have unity, on procedural votes. i think people can modify their views for the sake of unity. i agree with what peggy says. when the president said you did not build that, that was correctly jumped on.
